It was Mark, KC0D, a well know and very competent HAM. He was running his Igate unattended as he was out in the field as part of the Tracking and Recovery team. We have had conversations about this issue and he is at a loss for what is happening as are we all.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>Here is a snapshot of the telemetry from EOSS-159, the first flight of the day. Mark’s Igate is kc0d-3 in the snapshot. I haven’t broken out the delays to measure the delay time, but I don’t think it matters as there is an obvious problem that can be seen in the time stamps and the altitudes reported.<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>KC0YA-11>APRS,EOSS,qAR,<span

I'd like to see packets it delayed that were not digi'd by another station proir to it gating them to APRS-IS. If it was digi's by anything else, then the assumption can be disputed.
